Abstract:
Considering the growing importance of biofuels in Brazil and throughout the world, and taking into account that glycerol is a surplus byproduct of biodiesel production, the present study aimed to evaluate the production of cellulases and xylanases by Peniciliium echinulatum, mutant strain S1M29, using different concentrations of glycerol as a carbon source in combination or not with cellulose. Experimental use of 50% glycerol and 50% cellulose showed promising FPA activity, however, this was only approximately 50% of that obtained by previous studies employing only cellulose as a carbon source. More relevant was the fact that the enzyme broth prepared with 50% glycerol and 50% cellulose proved to be efficient in the hydrolysis of lignocellulosic biomasses, especially for elephant grass pretreated by steam explosion.
